You have the following loans/debts:

Loan	Interest Rate (Nominal)	Payment (monthly)	Remaining Payments	Current Balance
Car	9%	$288.95	37 payments	$9,305.71
Student	5.4%	$353.08	108 payments	$30,148.89
Mortgage	7.35%	$1,104.29	19 years	$135,486.40
			Total:	$174,941

Would you rather...? Option A: Consolidate your three separate loans and refinance by taking out a new 19- year loan at 7.25%, borrowing enough money to pay off all three existing loans?

Option B: Consolidate your three separate loans and refinance by taking out a new 30- year loan at 5.3%, borrowing enough money to pay off all three existing loans?

Explain your reasoning mathematically.
